Abstract

The utility model relates to a vertical corn thresher, comprising an outer cylinder fixed on a frame, and an inner cylinder coaxial with the outer cylinder driven by an electric motor, wherein, the outer cylinder is a cone with a bigger upper part and a smaller lower part, and the inner cylinder is in the shape a cylinder. The inner and the outer cylinders are both composed of squirrel cage shapes by upright stanchions connected with an upper and a lower rings of the inner and the outer cylinders, and each upright stanchion is provided with a convexity. Corn cobs enter the middle of the inner and the outer cylinders from the upper part. Driven by the cage-shaped inner cylinders, the corn cobs are under a grinding force and a tangential force, gradually threshed in the process of descending. The thresher has the advantages of higher percentage of threshing and no damage of the corn cobs.

Description

Vertical corn thresher

The utility model belongs to the sheller unit of crops, specifically a kind of husker sheller.

At present, known corn threshing device has hand-held thrasher and thresher.The former does not still break away from heavy manual labor, and efficient is extremely low; The most structure of the latter is complicated, and volume is bigger, is applicable to large-scale production.Chinese patent 2066229 discloses a kind of husker sheller, and it has an outer sleeve and inner sleeve.Outer sleeve is equivalent to the supporting of inner sleeve, and the inner sleeve front end has the Buddhist gripper, utilizes this pawl rotation with corn rod threshing.This thrasher must be singly with the corn ear feeding, so take a lot of work, time-consuming, its efficient is also very low.Chinese patent 1004243A discloses a kind of vertical thresher; inner/outer tube is the awl tube; the radial spacing of the inside and outside tube of this thresher each section vertically equates; so need regulate the radial spacing of inside and outside tube when using; utilization rolls the mode threshing, thereby still exists threshing performance not really high and disrepair phenomenon arranged.

The purpose of this utility model provides the small-sized vertical corn thresher that a kind of threshing performance height, order do not have disrepair phenomenon.

The solution that realizes the utility model purpose is: the vertical corn thresher that is provided comprises a urceolus that is fixed on the frame; one by motor-driven and the inner core coaxial with urceolus; wherein urceolus is up big and down small taper shape; inner core is cylindrical; the vertical rod of upper and lower ring constitutes the mouse cage shape to inside and outside tube by being connected in separately, and each vertical rod is provided with projection.Corn ear enters between the inside and outside tube from the upper end, under cage shape inner core drives, between corn ear and the vertical rod, produces relative motion between corn ear and the corn ear.Owing in the vertical rod projection is arranged, the space between the inside and outside in addition tube diminishes downwards gradually, and the iblet on the corn ear has been come off gradually, and corncob then comes out from inside and outside tube lower end.

Compared with prior art, of the present utility model simple in structure, in light weight, be convenient to move, so be specially adapted to disperse peasant household or small-scale corn threshing.Because the utility model has adopted the inside and outside tube of mouse cage shape, and the work section between inside and outside tube reduces from the top down gradually, and corn ear existing rolling between inside and outside tube has mutual slip again.Be that corn ear had both received certain grinding pressure, receive certain tangential force again, so the percentage of thresh is higher, and corncob can be not damaged.

Below in conjunction with accompanying drawing content of the present utility model is illustrated.

Fig. 1 is overall structure figure of the present utility model.

Fig. 2 is the profile diagram of inside and outside tube upper port among Fig. 1.

As shown in Figure 1: taper urceolus 1 is fixed on the frame 2, it by last ring 11, down encircle 12 and vertical rod 13 constitute shape such as mouse cage shape.Spiral is adopted in vertical rod 13, and many thread protrusion 14 are arranged on it.Inner core 3 is cylindrical, by last ring 31, down encircle 32 and vertical rod 33 be welded, shape such as mouse cage shape, wherein vertical rod 33 also adopts the axis 24 of spiral inner core 3 to be supported in that the side at urceolus 1 is equipped with motor 5 on the bearing 41,42, during its motor rotation by driving inner core 3 rotations behind belt transmission 6 and a pair of gear 7 double reductions.Spacing between the upper port of inside and outside tube is about 6cm, spacing between the lower port is 2.8～3cm, the inner core rotating speed is that per minute more than 300 changes, power of motor is 500W, corn ear is sent into for the ease of charging from the both sides of urceolus upper end, the circular arc feed nozzle 8 that one section evagination is respectively arranged in the both sides of urceolus upper end, as shown in Figure 2.

This thresher is specially adapted to the threshing of dried corn ear.

Claims

1, a kind of vertical corn thresher; comprise a urceolus (1) that is fixed on the frame; one by motor-driven and with the coaxial inner core (3) of outer (1) tube; it is characterized in that urceolus (1) is up big and down small taper shape; inner core (3) is cylindrical; inside and outside tube is gone up by being connected in separately, and the vertical rod of following ring (13,33) constitutes the mouse cage shape, and each vertical rod (13,33) is provided with projection (14).

2, husker sheller as claimed in claim 1 is characterized in that said vertical rod (13,33) employing spiral.

3, husker sheller as claimed in claim 1 or 2 is characterized in that respectively there is the circular arc feed nozzle (8) of one section evagination both sides in urceolus (1) upper end.
